Students/Graduates

Many of our fastest-growing specialties didn’t exist ten years ago, and colleagues just beginning their careers here played key roles in developing them. You can help create the opportunities for the next five years. We’ll provide the global platform to realize them – and all the training and support you need to lead the way.

Our Business

We help leaders in more than 130 countries deal with what matters most: the future of their organizations, people’s health, wealth and wellbeing, and how to survive and thrive. The majority of our colleagues do client-facing work, but some of us have functional roles, guiding our global enterprise.

Meet our Colleagues

"To me, diversity and inclusion unlocks potential and creates a space where talent can thrive — which is exactly what I’ve found while working at Marsh & McLennan Companies. As an Asian-American female member of the LGBT community, I want to share my experiences and learn from and work with others to increase awareness, value, and celebrate each other. I have had the honor and opportunity to be part of many diversity and inclusion initiatives at MMC and I truly feel that I am making a difference."

Rory JohnsonVice President, Marsh — London

"My team is very small with only three members in the London office, so there is a personal dynamic which creates a great atmosphere to work in. I have constant communication with my manager and team leader, so I can deal with any issues quickly and efficiently. My team, along with all the Marsh colleagues I have dealt with, are very approachable and always keen to hear good ideas, contributing to an innovative and enjoyable working environment."

"One of the best things about my job is the chance to be creative and to find innovative firms and strategic partners who can help our clients grow and also enhance GC's service offerings."

Rhys McKinnonPrincipal, Mercer — Melbourne

"I love working with Mercer’s clients, assisting them to implement our suite of solutions, and helping them to achieve better outcomes for their employees and customers. Working at a firm with the size and reach of Mercer, and within the Marsh & McLennan group of companies, has taught me the importance of tapping into our large network of remarkable colleagues. We have the luxury of asking questions, seeking advice, and collaborating with people from diverse backgrounds around the world."

Olga DrawskaBusiness Analyst, Oliver Wyman — Warsaw

"I have always believed in equality in every aspect of life. We're different, but equal; equal, but different. Diversity is a great asset — a melting pot of creativity. Inclusion is a sense of belonging, a friendship."
